创建MS SQL Server查询以确定排名

我正在创建一个应用程序，用户可以在其中进行训练。他们通过应用程序传递结果，这些结果存储在SQL Server数据库中。结果以这种方式保存在SQL Server表中：

我想写一个查询，根据每个用户的最佳分数创建排名。这就是我迄今为止所拥有的，多亏了这一点：

这将生成以下内容，其中根据用户的最佳分数创建排名：

当某个用户提交新的训练时，我想根据上次提交的训练检查他的排名，并与其他用户的最佳表现进行比较。所以假设用户_id 2添加了一个新的训练，他的分数是，比如说，12，那么基于这个新的表现，他目前的排名是多少？如果是那样的话，他在这张桌子上排名第二。谢谢。

试试这个：

DECLARE @CurrentUser INT = 5;

WITH DataSource AS

    SELECT id, 
           workout_id, 
           level_id,

           total_time, 
           score, 
           datetime_added,
           ROW_NUMBER() OVER (PARTITION BY user_id ORDER BY score DESC, datetime_added DESC) rowID
    FROM nodefit_rankings_fitness 
    WHERE user_id <> @CurrentUser
